  • the present invention relates to PC card socket connector and PC cards having such socket connectors.
  • PC cards have a front socket connector for connection with a mating connector when it is inserted into equipment.
  • a conventional PC card 51 have a metal ground plate 53 with a plurality of semi-circular projections 52 provided in the outer face of a front end portion.
  • the semi-circular projections 52 projects from the ground plate 53 so as to make sure contact with a shield plate of the mating connector.
  • an outer metal panel 54 is provided.
  • the panel 54 has a cutout portion 54A in the front end portion so as to expose the semi-circular projections 52.
  • the PC card 51 has a socket connector 55 at the front end for connection with a mating connector 71.
  • the socket connector 55 has a number of female contact elements 56 (of the rectangular cylinder type) arranged in two tiers in a direction perpendicular to the sheet for connection with male connector elements 72 of the mating connector 71.
  • the contact elements 56 have upper and lower tongue portions extending diagonally rearwardly from the front edge to make sure contact with the mating contact element 72.
  • a contact portion 56A extends rearwardly from the rear end of each contact element 56 for contact with a corresponding signal circuit provided on an inner board 58. Ground circuits are provided between the signal circuits arranged on the inner board 58 in a direction perpendicular to the sheet.
  • the ground plate 53 provided on the upper face of a housing 57 has a ground terminal 53A which is bent diagonally downwardly at the back of the semi-circular projections 52 to make resilient contact with the ground circuit of the inner board 58.
  • the ground terminal 53A runs under the panel 54 from the cutout portion 54A of the panel 54.
  • a shield plate 73 is provided on the mating connector 71 so as to have a front contact portion folded back into the PC card receiving recess 74.
  • the panel 54 Since the thickness of PC cards is regulated by the standards, it is necessary to provide the panel 54 with the cutout portion 54A where there is the ground plate 53 of the socket connector 55. Consequently, there is no shielding at a gap between the ground plate 53 and the cutout portion 54A of the panel 54. In addition, the cutout portion 54A reduces the strength of the panel 54. Moreover, the cutout portion 54A permits dust and/or water to enter. Also, it makes the appearance poor.
  • the socket connector is provided at the front end of a PC card.
  • the PC card has an inner board on which signal and ground circuits are provided. These circuits have contact portions for contact with the corresponding contact elements and ground plate of the socket connector.
  • the socket connector has a number of contact elements extending through the receiving holes of a housing.
  • Each contact element has a connection portion within the receiving hole for connection with the contact element of a mating connector and a contact portion extending rearwardly from the receiving hole for contact with the signal circuit of the inner board.
  • the PC card is provided with a metal panel which covers the entire card including the socket connector area.
  • a ground contact portion is provided at the front end of the panel for contact with the contact portion of the shield plate of a mating connector.
  • the housing has an attaching means to which an attaching portion of the ground plate is attached.
  • the ground plate has a plurality of terminals extending rearwardly.
  • the terminals consist of inner and outer terminals extending opposite directions.
  • the ground circuit on the inner board is grounded through the inner and outer terminals of the ground plate, the panel, and the contact portion of the shield plate on the mating connector.
  • the PC card is covered completely by the panel, leaving no gap at the socket connector. Thus, no dust enters the PC card and, also, the appearance is improved.
  • FIG. 1 is a plan view of a PC card according to an embodiment of the invention.
  • FIG. 2 is an exploded perspective view of an essential part of the PC card of FIG. 1;
  • FIG. 3 is a sectional view of the PC card and a mating connector before connection
  • FIG. 4 is a sectional view of the PC card and the mating connector in connection
  • FIG. 5 is a plan view of a conventional PC card
  • FIG. 6 is a sectional view of the PC card of FIG. 5 and a mating connector before connection;
  • FIG. 7 is a sectional view of the PC card and the mating connector in connection.
  • FIG. 1 is a plan view of a PC card according to an embodiment of the invention
  • FIG. 2 is an exploded perspective view of the essential part thereof
  • FIG. 3 is a sectional view of the connector before connection to a mating connector.
  • a PC card P includes a U-shaped frame 1 made from an insulating material, a socket connector 2 provided at the open front end of the frame 1, an inner board 3 connected to the socket connector 2, and a pair of upper and lower metal panels 4 and 5. These panels 4 and 5 are fitted in recesses formed by thin edge portions 1A and 6A provided on the front and back sides of the frame 1 and a housing 6 of the socket connector 2 and fixed thereto by appropriate means.
  • connection portions 3A of signal circuits are spaced at intervals on the inner board 3, and the connection portions 3B of the ground circuit are provided between the signal connection portions 3A (see FIG. 2).
  • a number of receiving holes are arranged in the housing 6 in two tiers widthwise (in a direction perpendicular to the sheet) and receive female contact elements 7.

  • the contact portions 7A have an inclined portion 7B for easy insertion of the inner board 3.
  • separation walls 8 are provided on the housing 6 between the respective contact elements 7.
  • the housing 6 has an attaching means 9 which has a pair of apertures 9A (FIG. 2) at opposite ends and an insertion space 9B (FIG. 3) formed between the separate walls 8 and the extended portion 6B of the housing 6 into which the flat portion of the ground plate 10 is inserted.
  • an attaching means 9 which has a pair of apertures 9A (FIG. 2) at opposite ends and an insertion space 9B (FIG. 3) formed between the separate walls 8 and the extended portion 6B of the housing 6 into which the flat portion of the ground plate 10 is inserted.
